O +: maitiro eboka reropa
36% yevanhu vekuFrance ndeveboka reO + ropa. Vanhu ava vanogona chete kugamuchira ropa kubva kuboka O uye vanogona chete kupa ropa kune vane rh positive (RHD +) zvidzidzo. Zvimwe zvidzidzo zvinoratidza kuti vatakuri veboka O vanodzivirirwa zvirinani kubva kutapukirwa necovid-19.
Boka O +: maitiro eiri boka reropa
Rimwe remapoka akapararira muFrance
MuFrance, boka reropa reO + ndiro rechipiri boka reropa (kuseri kweboka reropa reA +) sezvo riri iro boka reropa revanhu vanosvika makumi matatu nenhanhatu kubva muzana veFrance (vachipikisa 36% yeboka reA +). Sechiyeuchidzo, mapoka eropa asingawanzo zvikwata B neAB izvo zvine chekuita ne37% yehuwandu hweFrance.
Receiver chete kubva kuboka O
Musoro weboka O hauna A antigen kana B antigen. Saka anogona chete kugamuchira ropa kubva kuboka O nekuti serum yake ine anti-A uye anti-B antibodies. Mukuvapo kwemasero matsvuku eropa emapoka eropa A, B naAB, masoja ekudzivirira chirwere anoaparadza sokunge ari kurwisa utachiona. Tiri kutaura nezve hemolysis.
Donor chete kuRhesus + mapoka
Chidzidzo chiri muboka reO + chine rh positive (RHD +). Naizvozvo anogona kungopa ropa kune vanhu vane rh yakafanana (RHD): vanhu chete A +, B +, AB + uye O + vanogona kugamuchira ropa rake. Masero matsvuku. MuFrance, rh positive (RHD +) inowanzoitika pane rh negative (RHD-). Zvechokwadi, zvinenge 85% yevanhu vekuFrance vane rh yakanaka.
Sechiyeuchidzo, iyo Rhesus system (RHD) inotarwa zvichienderana nekuvapo kana kusavapo kweD antigen pamasero matsvuku eropa. Kana tikawana iyo zvinhu D inova antigen pamusoro pemasero eropa, iyo rhesus yakanaka (RHD +). Kana pasina chinhu D pamusoro pemasero matsvuku eropa, rhesus haina kunaka (RHD-).
Boka reropa chii?
Boka reropa remunhu rinoenderana ne maantigen iripo kana kusavapo pamusoro pemasero matsvuku eropa. Boka reropa rine seti yezvivakwa zvinobvumira kurongedza vanhu kuti vatsanangure kunyatsoenderana panguva kuwedzerwa ropa.
Mapoka eropa anotapurirwa nhaka, maererano nemitemo ye genetics. Iyo inonyanya kuzivikanwa yeropa system system ndeye rhesus system pamwe neiyo ABO system (inosanganisira mapoka A, B, AB uye O), akaonekwa muna 1901 saKarl Landsteiner (1868-1943), chiremba uye biologist.
Boka reropa O, iro ridiki rakakanganiswa necovid-19?
Kubva pakatanga denda reCovid-19, boka resainzi rave kufarira kubatana pakati peboka reropa revanhu uye njodzi yekuva neCovid-19. Sekureva kweINSERM, mugore rimwe chete, zvidzidzo makumi mana zvakaburitswa nezvenyaya iyi. Rimwe rebasa iri rakaratidza kuderedzwa kwengozi kune vanhu vane rudzi rweropa O.
Izvi zvabuda zvakatosimbiswa nezvakawanda meta-kuongorora.
Zvimwe zvidzidzo zve genome-wide association zvakaitwa muvarwere vakapinzwa muchipatara cheCovid-19 zvichienzaniswa nevanhu vane hutano vanonongedzawo munzira imwe chete. Iri basa rinoratidza kuti matunhu maviri ejenome ainyanyobatanidzwa nenjodzi yekutapukirwa, kusanganisira nzvimbo yechromosome 9 inotakura ABO gene inotaridza boka reropa.
Ndokumbira utarise, chokwadi chekuve weboka reO ropa hachibvisike munzira ipi neipi kubva kune zvipingaidzo, zviyero zvakajairwa zvekushamwaridzana uye kubaya. Vanhu veBoka O vanogona kutapukirwa uye kutapurirawo hutachiona.
